ZG3 tubular resistive elementDetailed product description：

1、 Purpose:
ZG3 tubular resistor element is used for regulating current in circuits below 380 volts. Resistors or transformers for various purposes can be formed by series connection, parallel connection, and grading of resistance elements according to requirements.

2、 Structure:
The resistance element is made by winding nickel chromium or copper wire around a porcelain threaded tube. The pipe hole can be installed through supporting components and the tapping head can be graded and tapped.
